    c: Fix boolean conversion of floating constant as integer constant
expression [PR113776]

    My fix for bug 111059 and bug 111911 caused a conversion of a floating
    constant to boolean to wrongly no longer be considered an integer
    constant expression, because logic to insert a NOP_EXPR in
    c_objc_common_truthvalue_conversion for an argument not an integer
    constant expression itself now took place after rather than before the
    conversion to bool.  In the specific case of casting a floating
    constant to bool, the result is an integer constant expression even
    though the argument isn't (build_c_cast deals with ensuring that casts
    to integer type of anything of floating type more complicated than a
    single floating constant don't get wrongly treated as integer constant
    expressions even if they fold to constants), so fix the logic in
    c_objc_common_truthvalue_conversion to handle that special case.

    Bootstrapped with no regressions for x86_64-pc-linux-gnu.
